This year has brought new evidence of what major fossil fuel companies knew and when about the role their products play in climate change, as well as what they did in spite of what they knew. But these technologies are no substitute for sharp cuts in fossil fuels if we keep the goals of the Paris climate agreement within reach.

Under the LCFS each fuel pathway gets a unique carbon intensity (CI) based on a lifecycle analysis of the greenhouse gas emissions associated with the production and use of the fuel. The CI of an electric vehicle charged with solar power is zero, and most of the biofuels fall somewhere in the middle [i].

Less than a quarter of cropland is devoted to food directly eaten by humans, with the rest going to mostly to animal feed and biofuel feedstock, and it takes many pounds of grains to produce a pound of beef. emit more methane than the fossil fuel gas system. Nitrous oxide is even more damaging to our atmosphere.

That report, in the technical language of probabilities and scenarios, underscored the urgency of the moment and the need not only to reduce the release of heat-trapping gases into the atmosphere and limit global warming to 1.5 Both options can increase water use , and biofuel production adds the potential for nutrient pollution of waterways.
